antialiasing for Fm

May 8, 2012 | 2:06 pm

Hi,
do you know how to built an antialiasing filter for FM?
It is useful to avoid foldover while using high modulation index…
Thanks

Thanks Brendan, I’ll take a look at it.

I’d recommend upsampling your poly~ to reduce aliasing. (use the up 2 or up 4 message)

Poly~ now has built-in high-quality resampling filters, so you get the anti-aliasing filtering on poly~’s output.
